Elon Musk’s tunneling venture, The Boring Company, is planning a massive citywide expansion of the currently modest underground transportation system it’s building in Las Vegas. The Verge reports: The startup now wants to build a 10-mile sub-surface “loop” that serves the famous Las Vegas Strip of casino hotels and reaches the city’s downtown area as well as McCarran International Airport, all with Tesla vehicles. The Boring Company also wants to build an additional loop that connects properties owned by Caesars Entertainment. The proposed new tunnels would make it possible to go from the Las Vegas Convention Center to Mandalay Bay in just three minutes, as opposed to 30 minutes by surface roads during peak traffic hours, the company claims. The plans, first reported by the Las Vegas Review-Journal, were detailed in proposals submitted to Clark County officials on Monday. The Boring Company’s expansion push comes just days after the Las Vegas Convention and Visitors Authority (LVCVA) finished buying the Las Vegas Monorail, which filed for bankruptcy in September after shutting down in March. Following the acquisition, the LVCVA killed a noncompete agreement that had previously kept The Boring Company from digging any tunnels that served the same areas reached by the monorail. The monorail is not expected to reopen until at least May 2021. Read more of this story at Slashdot.
